Texture not displaying properly in any mode except Texture Paint
Fjoersteller's comment:

Actually I think there is no need to re-upload. : ) Go to the Settings in the Material Properties tab of you material and. Under Settings you should set both Blend Mode and Shadow Mode  to Opaque. This should fix you problem.

Thanks Fjoersteller, that actually fixed it! I had Blend Mode on Alpha Blend, but turning it to Opaque fixed the texture completely!!!
